If you ask me the speakers on the HTC One are some of the best ever. The Boom Sound technology is outstanding. Both speakers include their own amplifiers for not only loud but also very clean audio. The Galaxy S4 is kind of lacking when it comes to the speaker when compared to the HTC One. If you would prefer your Galaxy S4 speaker to be much louder then you are in luck today. XDA member "boterkaaseneleren" has put together a mod. The mod wil work on both Touchwiz and AOSP roms. There are a few flashable zips included. You can choose "Very Loud", "Moderate", and "Back To Stock" Volume. Simply flash these mods in a custom recovery of your choice.
